Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Disk Performance Test
##################

This test is intended to test the performance of disk devices under Zephyr. It
was tested with SD cards, but can be used for other disk devices as well.
The test has the following phases:

* Setup test: simply sets up the disk, and reads data such as the sector count
  and sector size

* Sequential read test: This test performs sequential reads, first only over one
  sector, than over multiple sequential sectors.

* Random read test: This test performs random reads across the disk, each one
  sector in length.

* Sequential write test: This test performs sequential writes, first only over
  one sector, than over multiple sequential sectors.

* Random write test: This test performs random writes across the disk, each one
  sector in length
